WATCHMANS CLOCK.

SPECIFICATION forming part of Letters Patent No. 319,783, dated June 9, 1885.

Application filed March 12, 1885. (No model.)

To all whom, it may concern.-

Be it known that I, Runes B. CARR, of Boston, in the county of Suifolk and State of Massachusetts, have invented certain Improve ments in \Vatchmens Clocks, of which thefollowing is a specification.

This invention relates to that class of watchmens clocks in which a paper card or dial, or any equivalent thereforsuch as a strip of IO ribbon rotated or moved continuously by a time mechanism or clockis punctured by a stylus which is moved progressively over the dial byan electrically-released clock-movement, and is caused to puncture the dial during said movement by a succession of closures of an electric eircuit,which may be caused by the action of an automatic circuit closer and breaker acting when a watchman closes an electric circuit at a given point, the circuit closer closing the circuit a definite number of times, and therefore causing the stylus to make the same number of marks on the dial, so that when two or more styluses are arranged to act on the same dial each can be caused to make a different number or a diii'erent arrangement of marks, so that the acts of several watchmen may be recorded on a single dial.

The invention has for its object to provide improved means whereby the progressive movement of the stylus is arrested during each perforation or marking movement thereof, and a free inward movement of the stylus is permitted when its progressive movement is arrested; and to this end it consists in the im provements which I will now proceed to describe and claim.

0f the accompanying drawings, forming a part of this specification, Figure 1 represents a front elevation of an apparatus provided with my improvements. Fig. 2 represents a section 011 line x 00, Fig. 1, looking downwardly. Fig. 3 represents a perspective view of the portion of the apparatus having my improvements. Fig. 4 represents a section on line g 3/, Fig. 1.

The same letters of reference indicate the same parts in all the figures.

In the drawings, arepresents a dial or card,

go which is detach-ably secured by means of a spider, b, to a back plate, which is continuously rotated by a suitable time mechanism or clock, (not shown in the drawings,) the manner of supporting and rotating the dial being no part of the present invention.

0 represents a two-armed lever pivoted at d to the supporting-frame e, and having at the end of one of its arms a racksegment, f, and at the end of its other arm a sleeve, 9, in which is a spring-retracted stylus, h, which is adapted to be pushed outwardly by an electricallyoperated hammer, t, hereinafterdescribed, to puncture the dial.

j represents a time-movement the arbors of which are supported by the frame 6. To one of the arbors of said movement is alfixed a mutilated pinion, 7a, which, when the timemovement is not in operation, stands in the position shown in Fig. l, and when said movement is set in operation is rotated in the direction indicated by the arrow,its teeth being thus caused to engage with those of the racksegment f,and thus move the lever 0 toward the center of the dial, the stylus being thus caused to move progressively from the margin toward the center of the dial.

The hammerz' is pivoted in cars or brackets attached to the frame, and is provided with an armature, Z, which is attracted to the poles of the electromagnet m on when the latter is Soenergized and moves the hammer inwardly, causing it to strike the outer end of the stylus and push its pointed end against the dial at a point where the latter is backed by a rubbercovered arm, a. The portion of the hammer that bears on the stylus is extended,s0 that it can strike the stylus during any part of the progressive movement of the latter over the dial.

0 represents a lever pivoted at p to a post on the frame 0, and so arranged that the hammerz' in moving toward the dial will strike a pin, '1', on one of its ends, and thus force its opposite end outwardly. The outwardlyforced end of the lever 0 has a stop-pin or de- 9 5 tent, s, which, when the lever is in its normal positioni. 0., not displaced by the armatureleverstands so that it will arrest a pin, t, on a disk, a, rotating with the mutilated pinion 7c, the time-movement being prevented from operating when the detent s is engaged with the pin 2. Then the armature is attracted to the poles of the magnet, the hammer, acting on the lever o, throws out the detent 8, thus releasing the movement, the pinion 7c engaging and moving the lever c and the stylus until the engagement of the rack with the pinion ceases, in consequence of the mutilation of the latter, when the lever c returns by gravitation to the position shown in Fig. 1, the movement being at the same time arrested by the arrival of the pin t at the point occupied by the detent 8.

During the described movement of the stylus across the dial it may be pressed against the dial as many times as may be desired by successive closures of the circuit through the electro-magnet, thus making a series or row of marks on the dial, the number and spacing of which may be governed by an automatic circuit-breaker, so that during each operation the stylus will make a series of marks exactly like those made during every preceding operation, a distinctive series of marks being used for each watchman when the acts of two or more are recorded on one dial.

To insure the quick arrest of the timemovcment when the stylus is pushed against the dial, and the quick release when the stylus is withdrawn, 1 provide a lever, 'I), which is pivoted at w to a post on the frame 0, and is engaged at one end with the detent-carrying end of the lever 0, and is provided at its other end with an arm or stop, 0, projecting into close proximity to the pendulum a of the time-movement. The end of the lever 0 projects between a rigid shoulder on the lever 22 and the free end of the spring 6, attached to the lever v, a yielding or flexible connection between the two levers being thus provided. Nhen the lever 0 is displaced by the movement of the hammer 'i in pressing the stylus against the dial, its end,engaged, as described, with the lever 1), passes outwardly on the spring I), and thus turns the lever 12 on its pivot, and causes its arm 12 to press against and hold the pendulum, and thus stop the operation of the movement while the stylus is in contact with the dial. The flexibility of the spring Z) enables the lever 0 to be moved by the hammer after the lever 11 has come to a bearing on the pendulum, the spring I) yielding and permitting the lever 0 to move independently oft-he lever 12. A free inward movement of the hammer is thus permitted, said movement not being impeded by the bearing of the lever-arm c on the pendulum, as it might be if the flexible connection between the levers 0 1) were not provided.

The stoparm 1) may arrest the timemovement by comingin contact with any other suitable part of the movement-as, for example, one of the wheels. I prefer to have it come in contact with the pendulum, however, as described.

I do not here claim the laterally-movable stylus and the means whereby it is caused to move back and forth; nor do I claim the electrically-operated hammer arranged to strike the stylus during any part of its progressive movement, my present invention being confined to the arresting of the operation of the movement by a stop pressed against a suitable part of the movement when the stylus is pressed against the dial, and the flexible or yielding connection whereby the free inward movement of the stylus operating hammer is secured.

A strip or ribbon of paper, continuously moved by rotating drums or other devices, and arranged to receive impressions from the stylus, may be used as an equivalent'ol' the dial.

I claim 1. The combination ofthe rotatingdial or its equivalent, the stylus-carrying arm or lever, the time-movement whereby said lever and stylus are moved progressively, the electrically-operated hammer whereby the stylus is pressed against the dial,and astop-lever which is pressed against the moving part of the timemovement by the inward motion of said hammer, as set forth.

2. The combination ofthe rotating-dial, the stylus-carrying arm or lever, the tin1e-movement whereby said lever and stylus aremoved progressively, the electrically-operated hammer, and the movementstoppi11g devices operated by the hannner, said devices consisting of the two levers having a flexible or yielding connection whereby the free inward movement of the hammer is permitted after the stoppage of the movement, as set forth.

In testimony whereof I havesigned my name to this specification, in the presence of two subscribing witnesses, this 7th day of March,1885.
